Résumé 0

This paper presents the beginning of a three year pro ject which regroups four laboratories to develop and combine specific methods to extract information from optical and radar re- mote sensing data. Preliminary results are presented on three different information sources: airborne photography, space-borne multi-spectral images and SAR interferome- try, which respectively allow the compution of high reso- lution DTM, the detection of glacial lakes and the mea- surement of glacier surface velocity. Results obtained on two glaciers located in the French Alps are compared and validated with ground measurments.
